Here's a more detailed breakdown:
* Size: They are about the size of a large bumblebee, weighing only a few grams.
* Appearance: Their bodies are pink and wrinkled, with no fur, giving them a somewhat translucent appearance. Their eyes are tightly closed, and their ears are still undeveloped.
* Vulnerability: They are incredibly fragile and vulnerable, unable to regulate their own body temperature, move independently, or see or hear.
Since they are completely helpless, a mother squirrel will carefully nurture them in a secluded nest, providing them with warmth and feeding them milk until they are old enough to venture out.
